just one wee problem.....it is called U8 and it sits right in the middle so I cannot claw back the 25mm that you refer to.....the picture is a little misleading as I am holding the elbow towards me, check the turbo studs and direction I have marked where they point (either side of U8).....pipe was already inset into the flange Paul but I know what you are on about.....I will achieve the same result by cutting the diagonal line I drew on and re-weld it the flange is big enough to accept the greater length of the diagonal, maybe a little persuasion might be needed but the end result should leave me with the same sq area with maybe a very slight decrease in escape velocity of the exhaust gas
